RCU502 RCU501 Remote Controller Unit

RCU501 is a high performance, general purpose, real-time process control computer for use in a
wide variety of system applications in both on- and offshore installations. The processor core is
an embedded Power PC™ architecture and the module is approved for Ex Zone 2 applications.

The following built-in functions minimize system downtime:
• Extended Built-in Self– Test (BIST) for computer diagnostics and fault identifi cation during start-up and runtime
• Prepared for online remote diagnostics
• Prepared for online fi rmware upgrade
• Bootable from fi le server or local fl ash memory
• Easy installation and replacement
1. DIN Rail mounting
2. All connections are pluggable
3. 3 digit address switches
• Hot swap in redundant applications, dual and triple Hot-Standby redundancy, 1oo2 redundancy
• Status LED indication (Normal/Error)
• RoHS compliant

RCU502

• RCU501 performance is application dependant and governed by process
complexity, updating frequency and number of interfaced I/O. Maximum updating frequency is 50 Hz.
• Confi guration guidelines:
1. ESD/PSD: max. 800 I/O, F&G: max. 700 I/O both at scan rate: 1 Hz
2. Process/ Automation: max. 2000 I/O, design advice: 1280 I/O both at scan rate: 1 Hz
3. Anti-surge: 3 loops, Scan rate: 50 Hz
4. Dynamic Positioning: Triple redundant DP system combined with Position Mooring.

(Scan rate is adapted to signal processing and varies from 1 to 10 Hz).
